Imayini yamalahle enkulu kunazo zonke eShayina — Imayini yomgodi ovulekile i-Haerwusu. Imayini yamalahle itholakala e-Inner Mongolia Autonomous Region City, iZhungeer Qi Ordos (Xuejiawan) Eastern genera kule ndawo, eNyakatho yakhiwe emayini yamalahle e-Heidaigou Open-pit. Maningi ama-conveyor roller asetshenziswa emayini.Izinqolobane zamalahle ezibuyiselekayo zingamathani angu-17.3, ubukhulu bomthungo wamalahle obuyisilinganiso bungamamitha angu-21.01, isilinganiso sonke sokuhlubula esimaphakathi singama-cubic metres angu-6.626 ithani ngalinye.Impilo yesevisi yokuklama iminyaka engu-79.Imayini yokuqala yamalahle igcine amathani angu-6.36, ngesilinganiso sokuhlubula esimaphakathi esingu-4.099 cubic metres ngethani, nempilo yesevisi yeminyaka engama-32.

Imayini yamalahle yomlotha, isulfure ephansi, i-phosphorus ephansi, i-voltage ephezulu, inani eliphakeme le-calorific, indawo ephezulu yokuncibilika yomlotha wamalahle omlilo omude, owaziwa ngokuthi "amalahle aluhlaza", amalahle anamandla ekhwalithi ephezulu, anethemba elibanzi lemakethe. ubuchwepheshe bezimayini bezimayini zamalahle kanye nokulandela ngomkhondo ngefosholo elilodwa lokumba ibhakede kanye nokusebenza kokukhumula iloli kanye ne-dragline.Nsuku zonke isidlakela somhlaba esihlanganisa ithimba lezokuthutha elisindayo elizithululayo lihlangene lapha, lokhu kwaziwa ngokuthi "i-iron and Steel Group Mining toil" ngenxa yokujaha endaweni yezimayini zaseWujin, kwakha inani elikhulu.

Imayini yamalahle evulekile itholakala e-Ordos Plateau, okungenye yezindawo eziyingozi kakhulu zokuguguleka kwamanzi nenhlabathi eChina.Umsele wasekuqaleni umile futhi uvundlile, uhlaza aluncane, ukuguguleka komoya kanye nogwadule kubi kakhulu, kanti nemvelo yimbi kakhulu.Kusukela ekwakhiweni okuyisisekelo, imayini yamalahle yomgodi ovulekile izovunyelaniswa nokuthuthukiswa kanye nokuhlaza.Ukuthuthukiswa okunempilo kwemayini yamalahle kuhle emakethe yamarola okuthutha amalahle.

Imayini yamalahle enkulu kunazo zonke emhlabeni – iRochester.Imayini yamalahle itholakala ePowder River Basin of Wyoming, iyimayini yamalahle enkulu kunazo zonke emhlabeni enamathani angaphezu kuka-23.Imayini futhi ingenye yezindawo zamalahle ezinkulu kakhulu emhlabeni, zenkampani ye-Peabody energy.Minyaka yonke imayini ithenga ama-conveyor roller amaningi ezimayini.Umbhede wamalahle wemayini yamalahle yaseRochester uthatha amamitha angu-18.3 ongqimba olungaphezulu lwamamitha angu-76.2 futhi lunwebeka amakhilomitha angu-80.47.Imayini ihlanganisa indawo engamakhilomitha-skwele angu-258.9, okulingana nobukhulu beWashington, D. c..Kuthatha iminyaka engama-25 kuya kwengama-30 ukuqeda lezimayini.Ukukhiqizwa kwamalahle kwamalahle eRochester kwaziwa njengamalahle ahlanzekile kakhulu, isilinganiso sokushisa kwamalahle ngephawundi ngalinye lamayunithi ashisayo angama-8800 aseBrithani, kanye nesibabule esingaphansi kuka-0.2%.

Amalahle asebenzise ukuhlubula kwe-dragline overcast kanye nebhakede elilodwa kanye nobuchwepheshe bamaloli, athembele kumishini emikhulu, enemishini ephezulu, athuthukisa kakhulu ukusebenza kahle komsebenzi.Usuku nosuku, cishe uhambo lwezitimela ezilayishwe amalahle cishe uhambo oluyi-21 luzosuka emayini yamalahle e-Wyoming e-Rochester luye ezindaweni eziphehla ugesi ngamalahle eziyi-100 ezweni lonke.Ngisho namaloli amalahle apakwe embonini yezimayini zamalahle eRochester ayakwazi ukulayisha amathani angaphezu kuka-440. Idolobha laziwa ngokuthi "isikhungo sesithombe somhlaba", "idolobha lezimbali", njalo entwasahlobo, izimbali ziyaqhakaza, futhi ngaleyo ndlela "imbali idolobha” emhlabeni.
